Which Natural Fibres Are Used to Make Our Clothes?

If, as a society, we are to begin to see clothes in a different way, a way that places value on craft, skill and quality rather than disposability, one thing that can be easily communicated by brands and understood by consumers, is the fibres a garment is made of. 

Knowing where your clothes were made and who made them is a fantastic thing but knowing what they are made of and therefore understanding how to care for them, as well as how they might age over time, are also useful things to know when weighing up a purchase.

Fibres used in clothing can generally be split into two types ‘natural’ and ‘man-made’. They are spun into yarn, which can then be woven or knitted to make a clothing fabric or finished garment.


What is a natural fibre?

Plant fibres are collected from the seed cases, leaves or stem (bast) of a plant. These are cellulose-based fibres.

An animal fibre consists of the hair, fur or natural secretion (silk worm) of an animal. These are protein-based fibres.

It’s important to note that just because an item of clothing may be made of natural fibres does not necessarily mean it has not come into contact with chemicals somewhere along the processing chain

There are of course additional natural fibres used in textiles. The above graph outlines some of the most common of the natural fibres found in our clothing. 

Cotton is the most extensively used natural fibre.


What are some of the environmental issues surrounding natural fibres?

In the manufacture of animal fibres, animal welfare (e.g mulesing) must also be considered.


What are some of the pros and cons of natural fibres for us as consumers?



While animal and plant fibres are biodegradable (subject to how they are processed) and renewable resources, the rate at which we produce and consume them (often resulting in overgrazing and extensive land use) is not sustainable.
